Read from Karthus's seat: which stage windows this plan plays for against Ezreal.
This is Karthus's own plan; across 3,599 pooled games the lane is even.
| Stage | Favoured | Why |
|---|---|---|
| Level 1 | Ezreal | Ezreal favours L1 because Mystic Shot out-ranges your Q and refunds cooldown on hit. |
| Level 2 | Ezreal | Ezreal favours L2 because his poke plus Arcane Shift safety out-trade your immobile self. |
| Level 3 | Ezreal | Ezreal favours L3 because he pokes freely while you can't punish his blink safety. |
| Levels 4-5 | Karthus | You favour L4-5 because Defile flips the sustain and waveclear war back to you. |
| Level 6 | Karthus | You favour L6 because Requiem is a strong pick on a poke-Ezreal who's rarely full health. |
| First item | Karthus | You favour first item because Defile out-sustains his poke and lets you catch a used Arcane Shift. |
| Two+ items | Karthus | You favour 2+ items because your sustained AoE and R outscale his single-target skillshot DPS. |
Ezreal controls levels 1-3: Mystic Shot out-ranges your Q and refunds on hit while Arcane Shift keeps him safe, so farm with Lay Waste, dodge behind minions, and avoid getting chunked. He refunds his own cooldowns off hits, so the poke war is unwinnable and the farm race is not. Cast at the low minion, keep the mana high, and let the wave come to you. Wall of Pain covers the angle his support needs, so hold it until the two of them actually commit.
